Workplace safety is crucial. So is staying warm and comfortable. Our Tech Single Thick (Class 3) Pullover Sweatshirt helps you stay safe and cozy at the same time. We modified our Tech Single Thick Sweatshirts with 3M stretch reflective tape and two-tone high visibility yellow and black fabric to make it meet ANSI/SEA specifications. That’s a whole lot of safety and comfort combined into one hi-visibility hooded sweatshirt.
